Properties of Tephrite

Physical Properties of Tephrite

Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Tephrite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Tephrite rock are vital in determining its Tephrite Texture and Tephrite Uses.

Hardness and Strength of Tephrite

The physical properties of Tephrite depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Tephrite is 6.5 whereas its compressive strength is 90.00 N/mm². Streak is the color of rock when it is crushed or powdered. The streak of Tephrite is bluish black whereas its fracture is uneven. Luster of Tephrite is the interaction of light with the surface of Tephrite. Luster of Tephrite is subvitreous to dull. Tephrite cleavage is crenulation and pervasive. The specific gravity of Tephrite is 2.86. Tephrite is opaque in nature whereas its toughness is 2.4. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
